To all whom 'it maywconcernf Be it known lthat I, AUGUST E. Zoon, a citizen of the United States, and a residentof Vaterville, int/lie county of Lucas and State of Ohio, have invented a certain new and useful Agricultural Tractor;-and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyand to the figures of reference marked thereon, which'form a part of this specification.

My invention relates to motor trucks, and has for its object theprovision of an improved and highly efficient machine of this class which is simple, strong-and durable in its construction, easy of operation, and in expensive of manufacture, and which is provided with simple and efficient means for controlling the lowering .or raising of the usb-bars and the simultaneous throwing of the crank-shaft to which they are attached intoor out of commission with the actuating mechanism, as the case maybe.

The invention is fully described in the following s eciiication and a referred embodiment o same illustrated 1n the accompanying drawings, in which,-

This application is a division of an application filed May 23, 1908, and allotted Serial No. 434,613.

Referring to the drawings 1 designates the frame of the machine on which 4the bodyl or platform is mounted. This frame is supported by the usual frontl and rear axles 2 carried by lwheels 3, the rear ones only of which are shown in the drawings.

The power shaft of the machine is designated 4 and lmay be driven by any suitable motor. This shaft is mounted in suitable bearings longitudinally'of the frame at the middle thereof, and is provided with a' 'shifting-gear 5y which is controlled by a shifting-lever 6,' and may be moved into or fout 'of meshwith a gear 7 carried by the shaft 8. The shifting-lever 6 has connection through a rod 9 with a controlling-lever 10 fulcrumed to the framey 1 as at 11. The shaft 8 -is mounted in suitable bearings longitudinally of the shaft 4 and carries a bevel gear'12 at its rear end in mesh with and operating a beveled and differential gear 13 on the jack hangers 28 connected or cross shaft. 14 mounted transversely of the frame 1n suitable bearlngs .provided therefor. This shaft carries sprocket Wheels 15 at its ends which are connected Vto sprocket-wheels 1G on the hubs of the rear wheels 3 by means of the sprocket chains 17, thus providing drive means for4 the rear wheels of the truck. The shaft 14 also carries at one end al spur-gear18, which, through an intermediate shifting-pinion 19, on a stub shaft 20, drives av gear 21 on one end of a crank-shaft 22. This crank-shaft is mounted transversely of the frame 1 and is shown in the present instance as having 4 cranks set on quarters to each of which the forward end of a push-bar 23 connects. Each'of these push-bars is provided at its foot with a conical block or enlargement 24, which has its small end forward and aspur 25 projecting centrally from its rear or large end, to facilitate a irm engagement ofthe same with the surface over which they are traveling when in action. Q3 trail under the rear of the machine and work through vertically elon ated openings 26 in a guide-plate 26 whic is suspended beneath the machine transversely thereof by arms 27 connected-t0 the shaft 22 and by toi arms 29 projecting from a cross-shaft 30. This .cross-shaft is journaled in the frame 1 and hasa crank arm 31 connected, by a rod 32, to a' hand lever 33, which hand lever controls the oscillation of the shaft' 30to effect a raising or lowering of the guide-plate 2G and pushframe 1 beneath thel The push-bars e bars. The pinion 19'is also shifted on its Y that the crank-shaft mechanism when the pushwith the driving bars arc lowere into operative posltion and vice versa. It is thus apparent that I have provided both Wheel and push-bar propeller mechanisms Which are capable of acting together to propel Jthe vehicle and simple and eilicient means, for throwing `the push-bar mechanism into driving commission when the push-liars :are lowered, and of *discon-` necting such mechanism from the driving mechanism when the push-bars are raised.

'-l Wish it understood thatY my invention is not limited to any speciic construction or arrangement ,ofthe parts except in. so far 1. In a motor driven vehicle, rthe combij` nation of the drive Wheels,l a crank shaft,

pusher bars attached to the crank shaft, a driven shaft, mea-ns connecting said drlven shaft and drive Wheels for communicating rotation from one tol the other, a gear on each of said crank and driven shafts,a shiftable pinioncap'able of'movement to `mesh vice versa.

With said gears, and means operative to simultaneously lower vthe pusher bars and i shift saidy pinion to mesh with said gears and 2. In a motor driven vehicle, the 'combination of the drive wheels, a driven shaft in driving connection with such wheels, a crank sha-ft, pusher bars attached to such crank' shaft, a. guide member for such pusherbars capable of vertical movements to raise and lowerV such bars, a gear' on each ofsaid shafts, a pinion shiftalole` to'release or engage such pinions, and means operative by the movement of a single lever 'to eiect aloWer-ing and raising of said guide member 'and movements of the pinion to engage or release said gears. l

In testimony whereof, I have hereunto signed my name to rthis specification .in the presence of two subscribing Witnesses.'
